Container loading calculator and 3D load planner
Yaurapulse Loading Assistant estimates how cartons and pallets fit into standard containers, box trucks or a custom load space. Enter cargo dimensions, quantity and weight to compare capacity, payload utilization, unloaded items and practical loading steps.
Supported load spaces
Use presets for 20GP, 40GP, 40HQ and 45HQ containers, box trucks from 4.2 m to 13 m, or enter custom internal dimensions, volume and maximum payload.
Preset sizes are reference values for early planning. Always confirm the actual container or vehicle specification before loading.
What the calculation checks
Start with length, width, height, quantity and unit weight. The planner checks permitted orientations, door entry when known, geometric fit, support and payload. Carton layers are calculated automatically. Specified layer, bearing and floor limits add further checks.
The default allowance is 90% of usable capacity, reserving 10% to reduce the risk of cargo not fitting during actual loading. You may select 100% instead; the calculation follows your selected cap. Physical volume and clearance reservations are reported separately. A load must still pass geometry, support and payload checks; cubic volume alone is not a fit guarantee.
What the result includes
Each result reports requested, loaded and unloaded quantities, limiting reasons, physical and reserved volume, centre of gravity, weight distribution and loading steps. Multiple load spaces draw from one cargo manifest without duplicating quantities. Background calculation can be cancelled; 3D previews may display a subset while counts retain the complete calculated plan. Layout edits use the same constraints.
Planning limits
Default carton stacking produces a spatial loading plan. Entered bearing limits apply to carton columns, including loads transmitted by stacked assembled pallets. Optional measured equipment, axle, contact-pressure, acceleration and restraint inputs enable additional model checks. Incomplete checks are shown as unverified. Straight rigid-load routes do not simulate articulated forklift turns or every lashing geometry; this result remains a planning estimate.
For packing and securing practice, consult the IMO/ILO/UNECE CTU Code and the equipment operator’s instructions.
Container loading calculator FAQ
What information does the loading calculator need?
Choose a container or truck and enter length, width, height, quantity and unit weight. Standard load-space parameters are supplied automatically. Cartons are kept upright and may stack to the available height by default. For already-loaded pallets, enter the complete pallet dimensions and gross weight. Layer, bearing, door and floor limits are optional settings.
Which container sizes are supported?
The built-in container presets are 20GP, 40GP, 40HQ and 45HQ. Box-truck presets from 4.2 m to 13 m and a custom load-space option are also available. Preset dimensions are planning references and should be checked against the actual equipment.
How is the planning volume allowance applied?
The default allowance is 90% of usable capacity after dimensional margins, reserving 10% to reduce the risk of cargo not fitting during actual loading. You may select 100% instead; the calculation follows your selected cap. Physical cargo volume and clearance reservations are reported separately; neither allowance establishes packaging strength or cargo securing.
Why does the plan leave some cargo unloaded?
Cargo can remain unloaded because of dimensions, permitted orientations, clearance, support, specified bearing or operational limits, volume allowance, payload, or a finite search that found no further placement. Each cargo line reports the applicable reason; a heuristic result is not proof of the global maximum.
Does pallet mode include pallet limits?
Already-loaded pallets use their complete dimensions and gross weight, including the pallet base and tare. Palletizing cartons uses a selected pallet specification and adds its tare weight. Loaded pallets stay on the floor by default; stacking can be enabled, with optional layer and bearing limits.
Can this result replace a professional loading and safety check?
No. The result is a planning estimate, not a loading certificate. Confirm actual internal and door dimensions, payload and axle limits, weight distribution, center of gravity, securing, packaging, dangerous-goods rules and local regulations before loading.
